Today on Marine Science Minute with Florida Sea Grant: Vessel discharge laws!

Several white boats and sailboats rest docked at a wooden pier stretching into calm blue water under a bright sky filled with large, puffy white clouds. Two small, dense green mangrove islands sit to the left of the dock, while a few isolated palm trees stand on the shore to the right

If you’re out on the high seas, it’s important to know where you can and can’t dump your boat’s waste.

If your waste hasn’t been treated by a Coast Guard approved Type I or II Marine Sanitation Device, or MSD, you can’t dump it into state waters that extend three nautical miles off the Atlantic coast and nine nautical miles off the Gulf of Mexico coast.

If your waste has been treated through a Type I or II MSD, you still can’t dump it in any No Discharge Zone, freshwater lakes too shallow for vessels with installed toilets, or any river not navigable by interstate vessel traffic.

Here’s what you can do: download Pumpout Nav in the App Store or on Google Play to find a public pumpout station near you.
